Hi Product Hunt! I'm Carlos, a dad in Loveland, Colorado.

I built Biotadex because our family hikes kept turning into the same game: who can spot something new first, and what is it? I wanted an app that made that game real, so the kids would ask to go outside instead of being asked.

How it works: photograph a plant, bird, bug or mushroom, and Biotadex identifies it in seconds and adds it to your field guide. There's a Listen mode for birdsong, a living map of what people are finding nearby, sanctuaries you can visit, and crates on the map that drop numbered stickers you can collect and trade.

It's a solo build. I'm a developer and designer, and I built it with Claude Code as my main build partner.

It's free on iPhone and Android, with 10 free scans a week (15 in your first week).

I'd love specific feedback on two things: did the ID get your find right (and if not, what was it?), and what would make you open it on your next walk?

Thanks for checking it out!
